Migration

This is the documentation for etcd2 releases. Read etcd3 doc for etcd3 releases.

Snapshot Migration

You can migrate a snapshot of your data from a v0.4.9+ cluster into a new etcd 2.2 cluster using a snapshot migration. After snapshot migration, the etcd indexes of your data will change. Many etcd applications rely on these indexes to behave correctly. This operation should only be done while all etcd applications are stopped.

If you have a large amount of data, you can specify more concurrent works to copy data in parallel by using -c flag.
If you have hidden keys to copy, you can use --hidden flag to specify. For example fleet uses /_coreos.com/fleet so to import those keys use --hidden /_coreos.com.
